[QUOTE="Jeffdachef, post: 8692146, member: 650438"] we dont know its true ratings unless you do a clamp test or amp dyno. They have less since the coils travel a lot less. Impedance rise happens when a coil travels through a motor and in a sub you have a lot of movement depending on the Xmax. Mids and tweets, not even a fraction of that kind of movement means a lot less rise. I wouldnt worry too much about overpowering mids and tweeters, They have a tendency to have a sharp spike in the frequency response when the speaker is stressed and has clear signs to back down the gain. Plus you only need enough to get proper output for your listening needs. You dont need to max out the output of the amp just so you can max out the amp which leads to much higher THD vs an amp with headroom which leaves you in the clear almost non existent THD levels if you are only using 80% of the amp or less. Your noise floor, efficiency and everything will be better. [/QUOTE]
